The present invention is an improvement on my patent for Cantilever Counter Stool, No. 3,003,730, issued October 10, 1961.

In my Patent No. 3,003,730, adjustment of the under structure for the support tube was effected by a metal cone which was adapted to expand a horizontal support tube against a tubular sleeve which acted as a foundation member and was xedly secured by suitable means to the floor. I have found that adjustment of the under structure was often diiilcult as the metal cone sometimes cracks any welds in the construction and would oftentimes bind in the tubes and not allow release thereof for adjustment.

The present invention overcomes the objections to use of a metal cone in the under structure and objects of the present invention are to provide a construction which will not bind, allow release of parts of the under structure, and which eliminates any shock to the construction which might start the cracking of any weld.

Other objects include a cantilever counter stool construction which is easy to erect and adjust, permits ready replacement of parts if the support tube for said cantilever counter stool should become damaged, is inexpensive and generally superior to constructions now known to the inventor.

In the drawing:

FIGURE 1 is a fragmentary, side elevation, partly in section, showing the cantilever counter stool construction embedded in a concrete fill;

FIGURE 2 is a fragmentary, sectional view, on an enlarged scale, illustrating the under structure for securing a supporting tube for a cantilever stool;

FIGURE 3 is a fragmentary sectional view, on an enlarged scale, taken on the line 3 3 of FIGURE 2; and,

FIGURE 4 is a perspective view of a square washer used in the practice of the invention.

Referring to the drawing, the invention includes a support tube 1, one end 2 of which carries a rotatable stool 3 provided with a back 4. The stool base is provided with a center stud 5 having a crown type cam 6 which engages a transverse pin 7 within the support tube for automatically returning the stool to the position shown in FIGURE 1 when it is rotated by an occupant from counter facing position.

The support tube includes three angularly related members S, 9, and 10, all lying in the same vertical plane. Member 8 has the stool 3 mounted thereon. Member 9 is at an obtuse angle to the member 8 while member 10 is also at an obtuse angle to member 9 and constitutes a horizontal portion or a portion at right angles to member 8. Member 10 is termed the base tube and is the tube which forms one of the members of the under structure for the support tube 1 In the present instance, members 8, 9, and 10 of the support tube are substantially square in cross section, although other geometrical sections may be used. I provide two bracing tubes 11 and 12. Bracing tube 11 is within the obtuse angle member 9, the lower end of which joins with tube 12, tube 12 being within the horizontal base tube 10 and extends at its outer end to tube 9. The outer end of tube 12 is cut at an angle in order to join tube 9, as shown at 13. The inner end of the bracing tube 12 is cut at a right angle to the axis of tube, as shown at 14. Tube 9 is provided with an opening at 15 which communicates with the interior of tube 12 at the angular end portion thereof. Within the horizontal base tube 10 are a pair of spaced apart washers 16 and 17, the washer 16 abutting the end 14 of the brace tube 12 and interposed between the washers 16 and 17 is a block 18. Block 18 is formed of a resilient material which may be rubber or rubber composition or any semi-soft material, which block is of square cross section and fits within the horizontal base tube 10. The base tube is of square cross section, as has been previously set forth, and each side is provided with an enlarged transverse hole, as shown in FIGURE 3 at 19, 20, 21, and 22. Within the internal bracing tube 12, I provide an abutment washer 30 which is Welded or otherwise secured to the tube 12. The bore of the abutment washer 30 is in axial alignment with the bores of the washers 16 and 17, and the block 18 is provided with a transverse bore in axial alignment with the bores of the three Washers. An elongated bolt 31 has the shank thereof passed through the bores of the washers and the block 18. The head 32 of the bolt faces the bore 15 in tube 9. The bolt shank is threaded at 33 for engagement with the internal threads 34 of a nut 3S. The nut 35 is characterized in being provided with a bore 36 extending axially through the nut from the head 37 thereof to the threaded bore 34, the threaded bore being of lesser diameter than the bore 36. The head 37 is substantially square sectioned with the sides 38 tapering from end 39 to the shank 40 of the nut. It is intended that the tapered sides of the nut should be received within the square sectioned horizontal base tube 10, as shown in FIGURE 2. The outer end of the shank of the nut is cut so as to be in right angular relationship to the axis of the nut with this end abutting washer 17. To make use of the construction just described for the cantilever counter stool, and particularly to secure the under structure which includes the base tube 10 land elements within the base tube such as the bracing tube 12, washers 16, 17, and 30, the resilient block 18 and the bolt 31 and nut 35, the following structure is utilized.

In the present instance, and by way of illustration only, I assume that( there is a oor 50 and mounted upon the floor is a concrete lill 51 having a portion 52 adapted to support a counter 53 and a step portion 54 of lesser height than the portion 52. I assume that the floor line 55 is level and secured to the floor along the floor line are a pair of spaced apart brackets 56 and 57, the web 58 of the bracket 57 is of greater height than the web 59 of bracket 56. The bracket 57 has a ange 60 thereof secured by any appropriate means to the oor, as by a screw or screws 61. This is also true for the bracket 56, the lower flange 62 being secured by any appropriate means such as a screw 63, to the floor. A square-sectioned tubular sleeve 70 has one end welded at 71 to web 58 while the lower face of the tubular sleeve 70 is welded at 72 to the upper flange 73 of the bracket 56. The axis of the tubular sleeve lies horizontally, is level with the floor line 55, and extends outwardly from the front of the step portion 54. In the present instance I have provided a finish by covering the oor with terrazzo which also covers the front and top of the step portion of the concrete fill and the front of the ll 52. The tubular sleeve at its outer open end extends through the terrazzo covering, as shown in FIGURES 1 and 2. This type of finish forms no part of my invention but adds to the appearance. The under structure is inserted within a tubular sleeve '70, and while the horizontal base tube 10 may be adjusted outwardly, in the present instance it has been moved to a position where the tube 10 is joined to the obtuse tube members 9 and abuts the end of tubular sleeve 70. However, alignment of the counter seats will determine the position for the horizontal base tube. Assuming that the base tube is in correct position in both FIGURES 1 and 2, the bolt 31 may be turned within the nut 35 to draw the tapered head of the nut inwardly of the base tube 10. The shank end of the nut will bear against the washer 17 and as the washer 16 bears against the end 14 of tube 12, the block 18 is compressed. Compression of the block 18 will expand the block through the holes 19 to 22 into engagement with the tubular sleeve 70. The taper sided head of the nut will tighten securely within tube portion due to resilience of the block 18. Thus, the block 18 eliminates any shock to the under structure resulting from rough handling of the support tube and stool of a character which might be suicient to start a breaking of any of the Welded portions of the construction.

The operation, uses and advantages of the invention, are as follows.

It is assumed that the counter and its support structure have already been incorporated, together with the proper spacing for a series of tubular sleeves 70, the tubular sleeves being mounted upon or to suitable brackets such as shown at 56 and 57. The installers then place the support tube 1 in position with the horizontal base tube telescopically received within a tubular sleeve 70. The base tubes 10 t with close tolerance within the tubular sleeves 70 and each base tube 10 contains the members therein illustrated in FIGURE 2 at 12, 16, 17, 18, 30, 31, and 35.

During installation of the support tube, the nut 3S is loose within tube 10 so that the block 18 is not cornpressed. When the support tube 1 has been properly positioned so that it is in alignment with all other support tubes and the seats or stools 3 are properly positioned with respect to the front of the counter, each bolt 31 is turned to draw the nut shank against the washer 17 and the tapered head within the base tube 10. Such action compresses the resilient block and forces portions thereof to enter the holes 19 to 22 for engagement with the tubular sleeve. Such action frictionally secures the base tube 10 within the tubular sleeve 70. The resiliency of the block 18 allows the wedge shaped head 37 to tighten securely within base tube 10. Further the brace tubes and tubes 10 and 70 are locked together so that side sway of the support tube 1 is resisted.
